ABSTRACT:
A “Folded Cavity Surface Emitting Laser” (FCSEL) sum frequency generating device capable of generating a second harmonic at room temperatures with high efficiency and output power, while having a small size, low energy consumption, and a low manufacturing cost. A FCSEL sum frequency generating semiconductor diode laser has a multilayered structure that comprises a mode discriminating polyhedral shaped prism waveguide, which is located at one end of two light emitting diodes, a partial photon reflecting mirror, which is located at the opposite end of the two light emitting diodes, and a phase-matching sum-frequency generating superlattice, which is located between the polyhedral shaped prism waveguide and the partial photon reflecting mirror.
